To all 'whom 'it may concern:

Be it known that I, OsKAn GUNTHER, a citizen of the United States of America, residing at Kellogg, in the county of Shoshone and State of ldaho, have invented new and useful Improvements in Sash-Locks, of which the following is a specification. This invention relates to sash locks designed for the purpose of locking window sashes in place either when the windows are fully closed or when'they are raised to give ventilation in the room.

One of the principal objects of the invention is to provide a simple device for operating oppositely disposed spring bolts for locking the window sash at any desired position, and to provide means whereby said bolts may be locked in rejected positions, said lock being operate by a removable key.

Another object is to provide a sash lock in which the spring projected bolts may be locked by means of `a pivoted tumbler for holding the bolts projected, and a locking mechanism bler to unlock the same.

The objects and advantages above referred to may be attained by means of the construction illustrated in the accompanying drawing, in which,-

Figure 1 is a hqrizontal section taken through the bottom rail of a window sash and showing my sash lock in plan and partial section. Fig. 2 is a vertical section through the bottom rail of the sash and showing my sash lock in position for locking the window down. Fig. 3 is a central vertical section through the sash lock. Fig. 4 is a perspective view of the key for operating the lock.

Referring to the drawing for a more specinc description of my invention, the numeral 1 designates the window sash, 2 the window frame, 3 the parting strips, 4 the cleats, 5 the window pane and 6 the putty 1n the sash.

The bottom rail of the sash is provided with a horizontal openin 7 extending from the outer edge of the sas inwardly toward the center, and an enlarged recess 8 is provided in the center of the bottom rail. Oppositely disposed sliding bolts 9 are placed in the opening 7, the ends of said bolts being beveled, as at 10, to engage either an opening 11 in the metal strips 12 or to engage notches 13 in said strips. The outer ends of the bolts are guided through keepers 14, set

and key for operating said tum-V into the sides of the sash. The inner ends ofthe bolts 9 roject through a metal boxing 15 seated in t e recess 8 in the sash, said inner ends passing through threaded openings in the inner ends of a pair of finger holds 16, and a spiral spring 17 bears upon the iinger holds to force them outwardly and to project the bolts. 16 and pressing them together, the bolts 9 arereleased from the metal strips 12, and the sash may then be raised for the bolts to enga e any of the notches 13.

' o lock the bolts9 projected and in position to en age the holes 1 1 in the metal strip 12 a lock 1s provided, said lock consisting of a tumbler 18 pivoted at 19 to a pin 20 which is sup orted 1n the box or casing 1 5 at one end, W ile the opposite end is connected to a spring plate 21 which bears against the spring 17 and is mounted in the casing and secured thereto b means of a rivet 22. .To operate the tumbler 18 a rotatable lock 23 is mounted in the casing 15 below the tumbler, said lock having a proected inner end 24 which is pivoted in the p ate 21, as shown in Fig. 3, sald lock having an upwardly extending lug 25 which engages the tumbler 18. The lock is seated in a keeper plate 26 secured at the bottom of the casing. The tumbler 18 is provided with a downwardly rojecting lug 27 at one end and an upwar y projecting lug 28 at the other end, and at the sides of these lugs recesses 29 are provided.

A ke 30 havin a trian ular portion 8l which ts Within t e keyho e 32 1s used for unlocking the tumbler 18.

The operation of m invention may be briefly described as fo ows: enever it is desired to raise the Window sash, and the tumbler 18 is in locked position, the key 30 is inserted in the keyhole and turned to bring the lug 25 down out of contact with the tumbler to ermit the same to rock upon its pivot 19. he lugs 25 normally bear a ainst the Shanks of the fin er holds 16 to ho d the bolts 9 projected. en it is desired to raise the window the inger holds 16 are grasped .and the bolts 9 retracted. After the Window has been raised and the beveled ends of the bolts are engaged in the notches 13 the tumbler 18 may be turned so that the bolts 29 will engage the squared ortions of the finger holds and thus lock t e bolts in position.

My invention is of sim le construction, can be attached to a win ow sash of any By grasping the two inger holds kind, will o eratequickly and smoothly and can be pro uced at slight cost.

Having thus described the invention, What is claimed as new, is

1. A-window sash fastener compnsing op,-

` said lock having oppositely disposed ugs at its ends t'o engage t e inger holds, and a key for operating said lock. v

2. A sash fastener com rising oppositel disposed spring-actuated olts, finger holdss for retracting said bolts, a lock for locking `somos said bolts proected, said lock comprising a ivoted tumb er having a downwardly pro- ]ecting lug upon one 'end and an upwardl projecting lug upon the other end, a loc arrel mounted under the tumbler and pro-I- tn yided with a lug to bear a ain'st the bottom of the tumbler, and a key or operating said barrel. y'

In testimony whereof I aiiix my signature in presence of two witnesses. v OSKAR GNTHER. Witnesses:
